The IACG Campaign IV: Solar sources of heliospheric structure observed out of the Ecliptic

Abstract

The Inter-Agency Consultative Group, representing the four space agencies with contributing missions (the European Space Agency, the Japanese Institute of Space and Astronautical Science, the Russian Space Agency, and the United States National Aeronautics and Space Administration), has initiated a data analysis campaign “Solar Sources of Heliospheric Structure Observed out of the Ecliptic” (IACG Campaign IV) based on the unique capabilities and opportunities afforded by the core campaign missions, Ulysses and Yohkoh. The campaign is strongly benefited by data sets from solar ground observatories and other spacecraft missions (SPARTAN 201, IMP, WIND, SoHO). The campaign themes emphasize the joint analysis of these remote-sensing and in-situ data sets for features such as coronal holes, coronal mass ejections, and other solar sources of heliospheric structure.
